Hi there!
Recall the equation for gravitational potential energy:
U = GPE (J)
m = mass (48 kg)
g = acceleration due to gravity (9.8 m/s²)
h = height (21 m)
Plug in the givens and solve.
Addition of 2vector gives you 1large vector quantity
Answer:
Manometer is a measures to the atmospheric measure.
Barometer is a measure to the atmospheric pressure.
Explanation:
- Manometer is there are two types (1) closed tube (2) open tube, is filled with liquid water and mercury and the tube.
- Manometer do not need equal size of the tubes to the open ended manometers.
- Manometers is simple to attach on this filled to the high pressure gas in the bulb,this gas pressure put on the tube.
- Manometer is the attach the gas and vacuum gas to the open of the air, its high pressure gas is to the one of end.
- Manometer are filled the mercury to the heavy liquid manometer filled the liquid water and oil with the mercury.
- Barometer is to the close ended tube and the glass tube is the open and that a vacuum is the other end.
- Barometer can the u shaped and the closed ended tubes to the barometers.
- Barometer is the mercury closed end and vacuum is the tallest point in the liquid.
- Barometer is also used to be a table or left standing and also be digital and portable traditional glass, may find the digital clock .
- Barometer are filled the mercury to the high level liquid must be extreme tall in change in atmospheric pressure.
